Maybe if you disabled that device the au= dio would work better. Try doing: echo 0 >/sys/bus/usb/devices/1-1.4/bConfigurationValue and then trying the audio. There's also a video camera on that bus, but since it runs at high speed ra= ther than full speed, it probably isn't interfering significantly. If you want,= you can try disabling it also by issuing the same command with 1-1.6 in place of 1-1.4. --=20 You may reply to this email to add a comment.
